Not sure about what kit was used to record the demos and without a full studio, you will lose some on the quality, but...
I think that pretty much everyone who has built a guitar has been stoked with the outcome - if only because it is more theirs than any other guitar you will probably own. I've also found it's helped me to understand what goes on under the bonnet so to speak with a guitar so feel I have more than a passing chance to fix a guitar if I've got a mate with one that's broke.
